Abstract
To eliminate welded or soldered connections between the fine or thin secondary wire (18, 18a) of an ignition coil and the high-voltage terminal plug, the high-voltage terminal arrangement includes a tubular stub (19) having a conical opening (29) therein, within which the end portion (18a) of the secondary wire can be placed, preferably in form of twisted-together loops (28), and the connection is effected by a screw machine part (30) in form of a conical plug, press-fitted within the conical opening, and making electrical connection with the twisted wire, while being retained securely within the stub (19). After insertion, the plug, the primary and secondary windings, and the core can all be molded or potted by being surrounded with a plastic injection molding or a potting compound. The twisted wire ends can be pre-tinned, and the surface of the plug smooth; or the surface of the plug can be knurled, stippled or ridged to bite through magnet wire insulation.
